Well, the whole thing about Manafort that is so disingenuously stupid is that:
FACT #1: Manafort was the Trump 2016 Campaign chairman for only two months before he was forced to resign - because the Trump Campaign did not like Manafort's increasingly apparent Russian connections and believed he had not been honest with them about these connections.
FACT #2: The charges on which Manafort was convicted have absolutely nothing to do with Donald J. Trump.
FACT #3: Even though Mueller squeezed Manafort with his own misdeeds, there still is no evidence of any collusion by Trump with the Russians to overturn the legitimate results of the 2016 presidential election. HOWEVER, there is tons of evidence that the Clintons colluded with the Russians to hand over 20% of the U.S. uranium reserves in exchange for payola.
Therefore, it is patently ridiculous and deceitful to attempt to connect Manafort's legal troubles with President Trump.
